Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25556, here are decompositions:

19 + 25537 = 25556
103 + 25453 = 25556
109 + 25447 = 25556
199 + 25357 = 25556
313 + 25243 = 25556
337 + 25219 = 25556
367 + 25189 = 25556
373 + 25183 = 25556

Showing the first eight; more decompositions exist.
